Welcome

The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.

Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Uniform motion, uniformly accelerated motion, uniform circular motion, simple harmonic motion - what is the difference between all these types of motion? This episode covers the most common types of motion one may come across while studying physics in high school.

If you want to describe the motion of a moving body, you have at hand three important physical quantities: speed, velocity and acceleration. How is each one of them defined? What's the difference between average and instantaneous velocity? The answers and more in this third episode.

The Institute of Physics Schools and Colleges Lecture 2008. Delivered by science presenter and rock guitarist Dr Mark Lewney. Rock guitars, superstrings, 11 dimensions and the world's largest and highest energy accelerator are the prime ingredients for the loudest lecture to date. This lecture reveals how: rock guitars make their distinctive sounds; string vibrations might answer questions about the Big Bang; the LHC may let us peek into extra dimensions.

Ernest Rutherford's famous gold foil experiment involves the scattering of alpha particles as they pass through a thin gold foil. It led to a better understanding of the structure of atoms. It's also known as the Geiger--Marsden experiment, after Hans Geiger and Ernest Marsden who performed it under Rutherford's supervision.

Particle physicist Bruce Kennedy explains with this modern re-creation.

PS MESSAGE FROM PROF MORIARTY: "I misspoke for the last sentence of the video. What I meant to say is that the photons don't have enough energy to excite electrons across the energy gap and therefore light is transmitted. What I said was precisely the opposite, contradicting everything else in the video. Apologies for any confusion caused."

Garik Israelian is a spectroscopist, studying the spectrum emitted by a star to figure out what it's made of and how it might behave.

Pink Floyd fans will appreciate his reference to Dark Side of the Moon: "The power of spectroscopy was actually realized by Pink Floyd already in 1973. Because they actually said that you can get any color you like in a spectrum. And all you need is time and money to make your spectrograph. "
